Renew timeout when query is accessed via cache

[federicoemartinez]

If I understood correctly, every query is cached. If we configure a timeout and we use for instance redis, the key will expire after the timeout.

My question is: Is the timeout refreshed when a query is accessed again? I think this would be useful as it would allow to set a "low" timeout to avoid redis getting full of one time queries, but the most common ones will remain always in cache
